EDWARD WESTON, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF NEW YQRK, N. Y.

lNCANDESCENT-ELECTRlC-LAMP HOLDER.

SPECIFICATION forming part of Letters Patent No. 269,757, dated December 26, 1882.

Application filed August 23, 1882.

T 0 all whom it may concern:

Be it known that l, EDWARD WESTON, a subject ot'the Queen of GreatBritain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful 1m provementsin Incandescent- Electric-Lamp Holders, ofwhich the following is a specification, reference being had to the drawings accompanying and forming a part of the same. A

My present invention consists in holders for incandescent lamps, distinguished by certain novel and useful features of construction, by means of which a lamp is readily connected to the electrical conductors and securely held in place by the same. The construction and arrangement of the said holder is also such that the conductors aie entirely inclosed by the insulating material of the holder, and are connected to the terminals of the lamp in such manner as to be in a state of constant strain, thus insuring a perfect electrical contact, and serving to hold the lamp securely in position.

In the accompanying drawings, where the holder above referred to as forming the subject of my invention is illustrated, Figure 1 is a view of the same with a lamp attached, the holder being shown in central vertical section; and Fig. 2, a horizontal section of the holder, taken on the line a" wot Fig. 1.

The holder is composed of the two parts A and B, both molded or turned from any proper insulating material. The part A consists of a cup, the base a of which is provided with means ofattachment to a bracket-arm or equivalentsupport. In thepresentinstancea screwthreaded extension, 0, is shown, though other devices may obviously be used. In the upper portion of the cup A are slots 1) b,running obliquely down its sides, and over the cup A fits cap B, with pins 0 e, that register with the slots b b. In the top of cap B is cut a circular opening, forming a slot for the reception of the neck of an incandescent-lamp globe. Binding or screw posts C C pass up through the base a of cup A, and to their inner ends are connected comparatively stout metallic spirals D D. The upper or free ends of the will be securely held in position.

(No model.)

spirals are passed through a piece or plate of insulating material, E, and are then bent over into hooks.

A lamp to be used with the above-described holder has its conductors formed into hooks or eyesff at or near the points at which they enter the lamp. To attach the lamp, the cap B is turned so that the pins 6 e are brought to theirlowest position in theslotsbb. Thehooked ends of the conductors D D should then be sufficiently exposed to permit of the ready engagement therewith ot' the rings or eyes ff. The lamp, when thus connected, is drawn up, the spirals distended, and the cap B then turned until the pins 6 a rest on the edge of the cup A. In this condition of the. holder the lamp If the slots 1) b be formed with notches at intervals, or with only a slight inclination, the upper part or cap, B, may be made practically adjustable.

In other applications I have shown and described springs of various kinds for holding a lamp in place and completing the circuit through thesame. I am further aware that springs for this purpose are not broadly new, and I do not therefore claim the same herein; but,

Having described my improvements in connection with the said springs, what I claim 1. The combination of an incandescent lamp and a holder for the same, spring-connections between the conductors of the lamp and the holder, and a socket adjustable on said holder for raising the-lamp therefrom, whereby the springsare distended and the lamp held in place, as set forth. v

2. The combination of an incandescentlamp, a socket or holder composed of a cup, A, containing slots 1) b, and a cap having pins 6 e, and spring-conductors connected to the base. of cup A and to the wires of the lamp, substantially as above set forth.

3. In a holder for incandescent, lamps, the combination, with a cup or base, of spring-conductors secured to the same and adapted for connection with the conductors of a lamp, a 5 movable cap containingaseatforalamp'globe,

and means, substantially as described, for retaining the cap in a raised position on the cup, as and for the purpose set forth.

4. In a holder for incandescent lamps, the

combination, with a slotted cup, of spiral couductors secured in the base of the same, a piece or plate of iusulatin material, through which the ends of the spirals are passed, and a cap containing a seat for a lamp-globe and provided with pins arranged to register with to the slots in the cup, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 21st day of August. 1882.

EDWARD WESTON.
